LONDON — A celebration of free healthcare, the trade union struggle, the battle for women’s rights and a fleeting lesbian kiss: the Olympics opening ceremony Friday did not shy away from weighty social issues.

Unsurprisingly, the show devised by Oscar-winning British director Danny Boyle drew accusations from the British political right that it had strayed into “leftie” issues.

Aidan Burley, a lawmaker from Prime Minister David Cameron’s ruling Conservative party, tweeted: “The most leftie opening ceremony I have ever seen — more than Beijing, the capital of a communist state! Welfare tribute next?”

He followed that with: “Thank God the athletes have arrived! Now we can move on from leftie multi-cultural crap.”
